Integer Coded Differential Evolution Strategy and Application to Microwave Imaging

  • Received Date: 19 Sep 2007

  • Integer coding for a differential evolution strategy was proposed.For an optimization problem,the conventional solution space coded with real numbers is discretized into an integer coded space according to a given precision.Solutions were searched in the integer coded space while the fitness is evaluated in the real space.For engineering problems,the integer coding is efficient,and automatically filters unsteady solutions.As an example,the integer coded differential evolution strategy was applied to solve a microwave imaging problem,which was of discretization,high-dimension and multi-solution.The integer coded differential evolution strategy shows a higher searching speed and obtains better optimization results compared with the real coding.
